This is a lesson that failed the first time but through years of improvements has turned into a project that students love. If you teach rational functions, definitely check it out. #mtbos #iteachmath

The Power of Iteration in Teaching
I had a reflection the other day that came from observing the work of a teacher who I’ve now coached for four years.

This is one of my favorite end-of-unit tasks for Quadratics. I love seeing students’ creativity, so I wrote a post about it! #iteachmath #mtbos

I've been using a new format for intervention that I had to share because it has totally shifted how I think of support for students. #mtbos #iteachmath open.substack.com/pub/kristens...

Does anyone know about @desmos.com switching over the teacher site and activity builder to Amplify? All of my custom
activities were gone when I tried to log in—it says I have authored zero activities. I really hope that isn’t the case! Any help is appreciated #mtbos #iteachmath

Great description of a way to implement Thinking Classrooms that combines inquiry with explicit practice. This combines them across days while I combine them in a single lesson but the idea is that students benefit from both types of learning. #mtbos #iteachmath open.substack.com/pub/adrianne...
My Thinking Classroom
In the spring of 2022, our building’s instructional coach walked into my classroom and handed me a bright orange book.

I started doing this end of unit extension project for trigonometry and similarity where students can design their own roof truss. There were some pretty cool design this year! #mtbos #iteachmath

This problem was so much fun! It was really exciting to see how many different solution paths students could come up with to find the perimeter of the square. Beautifully knits together properties of trigonometry and Pythagorean theorem. #iteachmath #mtbos @illustratemath.bsky.social

I couldn’t agree more with @dylanpkane.bsky.social approach to online tools in the classroom. I use @desmos.com activity builder for my Warm Up questions each day because the batch feedback is so useful but I set a timer for 7 minutes and students close laptops before we debrief. #iteachmath #mtbos

This problem was great! A student said: “Wait but I just realized it also works if you switch them! Sin(41) still equals cos(49) even though it’s a totally different value!” And then another student said: “Wait, does it also work for 30 and 60?” And the whole class was like YES! 🤯 #iteachmath #mtbos

We launched trigonometry today in Math II. I’ve been using this resource for years and it’s still my favorite way for students to investigate the ratios. Students walk away understanding where the values in the calculator “come from”. #iteachmath #mtbos www.projectmaths.ie/documents/T&...

I love teaching right triangle trigonometry. Just when my Math II students start to think that math has taken a turn toward abstract symbols and equations and is not “real” enough, trigonometry shows up with all of its lovely simplicity and real-world applications. It really saves the day.
What’s a lesson or unit you look forward to teaching in the spring?

Our Math Team has mapped the math language routines onto the Teaching Through Problem-Solving lesson format. Teachers can see where there might be opportunities to integrate a MLR into the lesson. MLRs are not add-ons. They are essential.

I believe there is a lot of merit to the idea that explicit instruction is highly effective when done well and is key to effective instruction. I also believe inquiry can be highly effective when done well and @mrzachg.bsky.social focuses on the ways it can fall short when not done well. #iteachmath
